Well, cleaning the connector didn't help things. If I want to pursue this I guess I could change the O2 sensor but it's only about 3 years old and <10,000 miles. Not sure I want to do anymore: ^(

Didn't solve the problem. I'll pull the O2 sensor next and see what that looks like although it is relatively new so doubt that's the problem.

Looking at an O2 is hard to tell if it is good or bad.

I've heard of some O2's going bad after a year or so - Bosch mainly.....so the fact it was replaced 3 years ago does not rule it out.

 

From reading on here (in other threads) you really want to go with a Denso O2 sensor. It appears that they last the longest.

A side note: a lot of Bosch's products are being manufactured in 3rd world countries, so the quality might not be as good as it used to be. Just a heads up.

 

A friend I know has a 96 Canadian Accord that was having a "no code" drive ability issue. Upon first description, I suggested a lazy O2 but he ruled that out as it was replaced a year before.

About six months later it finally threw a code for the O2 - he had put a Bosch unit in it the year before. Replaced it with a Denso the next time and has been driving it for about three years now without any engine issues - is having a DRL issue right now but that is another story.

 

Well Poorman212 you were correct:^) Today I got to change the O2 sensor Denso) and that solved the problem. I looked up my records and the old O2 sensor went in March 2013 about 7000 miles ago when I replaced the exhaust pipe. What mislead me was the manual description of the 43 error. Although it starts by suggesting the O2 sensor, it also says if accompanied by poor drivability it's the fuel system. So I hit the O2 sensor last when I should have hit it first. Anyway now I know the fuel system is OK, the ignition is refurbished and the O2 replaced. About $120 in parts because there isn't a standard adapter for the fuel port, had to kluge one together.
Thanks all,

Congrats on fixing it.
The fuel adapter is available thru " thepartstree.com ", as it's also used on Honda Marine engines. They're getting 15 to 20 bucks for it, but, you still have to modify it so you can use a conventional pressure gauge on it. That's what I had to do for my 97 Accord to test pressure.

In talking with an old Mercedees mechanic, he tells you to go thru the check list of problem solving first. But more importantly, don't think, just do it. Tht's because if YOU start thinking, you'll only create new problems to solve. The engineers were pretty damn smart for you to "out smart". I look at it that way when going thru the Honda FSM too.
